Hybrydowa elektrociepłownia

  1. 1. Polish-German CooperationPresentation of Local Cogeneration Power Plant RENREN Monitoring Group & Steering Committee Joint Meeting Łódź, 7.06.2011
  2. 2. BMU programme for promoting investments in the reduction of environmental pollution abroad Aims of the funding:• Direct, measurable impact on the environment, including, in particular to reduce air and water pollutants, or• Presenting economic activities to improve the climate, in particular, reducing carbon dioxide emissions and replace fossil fuels by renewable energy sources.The intensity of co-financing: 30% -75% of eligible costsMultipliereffect, ie. The possibility of relocation of activities in a project designed for areas with a simila rsituation and the economic side of the project. Name of event
  3. 3. Primary Objectives:1. Production of green energy – reduce air pollution by reducing CO2.2. Solution model, which is an incentive for similar actions to other local communities. Name of event
  4. 4. DetailObjectives:1. Increase energy independence of Daszyna Commune.2. Cooperation with the heating plant in a situation of greater demand for energy (in winter).3. Take advantage of surplus of straw from local agriculture.4. Social-economic development of Daszyna Commune.5. Promotion of Daszyna. Name of event
  5. 5. Reduction of CO2 Coal Straw Heat of Combustion 23.8 MJ/kg 14.7 MJ/kg Pure Carbon content 97% 46% Ash content < 2% 6%Ammount of CO2 produced 4.07 kgCO2 6.8 kgCO2to obtain 100 MJ of energy Equivalent emmision of CO2 – 1.96 x 106 kg/year For biomass solution – 0 kg/year Name of event
  6. 6. Old heating plant Name of event
  7. 7. Cost estimation Name of event
  8. 8. ORGANIC RANKINE CYCLE ? 400 kWel TURBINE ~ ?BOILER Fan cooler2 MWt Pump Name of event
  9. 9. ORGANIC RANKINE CYCLE ? 400 kWel TURBINE ~ GeneratorBOILER Fan Cooler2 MWt Pump Name of event
  10. 10. Setup of power plant Name of event
  11. 11. BoilerThe boiler must be carefully chosen inorder to satisfy the plant requirements:1. Reliability2. Stability of parameters3. High efficiency4. Flexibility5. High temperature of water6. Dealing with straw burning problems
  12. 12. What is Rankine cycle?? Critical point 3 Qin W turbine21 4 Qout Name of event
  13. 13. Principle of RC Name of event
  14. 14. Principle of RC Critical point 50 bar Water saturated steam 3 Wet steam 0,06 bar21 4 Name of event
  15. 15. Parameters of ORCFUEL STRAW BRIQUETTEPRESSURE [bar] 2.68INLET TEMPERATURE [K] 348.15OUTLET TEMPERATURE[K] 403.15MASS STREAM [kg/s] 8.68POWER [kW] 2000 Name of event
  16. 16. Principle of ORC Critical point 50 bar 3 Critical point 3’ 2’ 0,06 bar2 1’ 4’1 4 Name of event
  17. 17. Turbine1. The turbine is an integral element in the cycle2. It converts the energy of the working fluid into mechanical energy3. The turbine must accurately match the given conditions of the localization4. Examples of turbine stages:
  18. 18. The conditions that a turbine should satisfy1.In case of the commercial projects - high reliability (one hour off is very expensive)2.High efficiency – it results in greater electrical3.Simple design – results in lower cost of the turbine
  19. 19. The concept for Daszyna1.Working fluid with high critical temperature (e. g. R141b)2.A few stage impulse turbine with rotational speed of 3000 rev/min (cheaper but less efficient solution)3.A few stage reaction turbine (more efficient but also more expensive solution)
  20. 20. Power generator1. Power generator – three phase asynchronous induction motor2. The turbine and the power generator combine to the turbogenerator
  21. 21. Other components1. Heat exchangers – must be reliable and well sealed (to prevent any leaks and mixing)2. Circulation pump – the best would be a hermetic one3. Control system – power plant must be fully automated4. Other elements – must withstand the conditions of the ORC cycle
  22. 22. The advantages1. The concept can be applied in other country regions due to availability of the straw.2. The cycle is flexible and scalable.3. The idea is innovative as it would be the first of this kind in Poland.
